Sorry if this has been discussed. My bike was stalling sporadically. Took to dealer for 11500 mile maintenance, still stalled. Took it back, was told it was fine. Started on trip to Denver from Portland, OR but after 50 miles it was missing horribly. Returned home, ran fine then (of course). This episodic problem is very hard to diagnose. Took a different bike on trip, sad to say. Any similar experiences, suggestions? Thanks in advance.
